Bill Cosby- Sexual predator orextortion victim?

[RStar]

From the tone of what I hear on here and in the media, it sounds like most everyone (myself included) thinks him guilty. But it's circumstantial evidence by hearsay. There's no real evidence, which is why he was able to get away with it for so long. And probably a good reason for the police to investigate, if only to bring the truth to light. So two questions:

Is it right for us to judge him guilty?

Did he do this on his own? Or did he have someone close to him that helped him, say get the drugs used or make sure he left no evidence? If so this could be the smoking gun.

My guess is that he is very intelligent and pulled it off himself, but a celebrity of his stature rarely is truly alone. So someone must have seen something.
